The operation of the device is as follows As is well known the oil in an automobile is changed about every five hundred miles. Consequently, when using this device the operator when changing the oil will note the number` of miles registered on this speedometer, and know that another five hundred miles it will be necessary to again change the oil. Accordingly, by inserting a pin to the slot 6 and engaging the end of the pin in one of the openings 10 of the slide plates 9 he will slide each plate longitudinally Vof the casing to bring a `certain number on each plate in registry with the slot to be observed therethrough. The total number which will then be observed through the slot 6 will be equal to or the sum of the total mileage registered on the speedometer plus five hundred so that if for example the total milea e registered by the speedometer is three t ousand one hundred and twenty-seven (3127) each of the slide plates 9 will be moved, so that the top or unit slide plate 9 will be moved to dispose the naught at the slot 6, and the remaining slide plates likewise moved to ,a position as to bring the numerals 3, 1, 2, 7, respectively, on each of the plates in registery with the slot 6 so that the numbers visible through the slot 6 will be 3, 6, 2, and 7 or 50() plus 3127. Manifestly then, the operator will know that when the speedometer registers the same distance as indicated yto agree with the numbers disclosed through the slot 6 that a change of oil must be made.

The corrugated inner lining 7 contacting with one face of each of the slide plates 9 vwill have a tendency to maintain the plates in aset position against casual displacement.

In that embodiment of my invention illustrated in Figures 5 to 7, inclusive, I provide a relatively thin circular casing 5a, the front wall of which is provided with a vertical slot 6 terminating inwardly from the periphery ofthe casing at one end of the slot, the other end of the slot terminating in spaced relation e to the center point of the casing. Arranged within the casing as shown to advantage in rFigure 6 are provided a plurality of rings 11, which rings 11 gradually increase in diameter from the center to the periphery of the casing 5a, said rings fitting one within the other, and adapted `to be individually rotated about one another. On one face thereof each of the rings 11 have arranged thereon a series of numbers ranging from naught to nine arranged'in circumferential spaced relation, the rings being further provided adjacent each of the numbers with a relatively small openings 12, whereby a pin inserted through the slot 6 and into one of the openings 12 the rings may be individually rotated for bringing any one of the desired numbers int-o registry with the slot 6 to be viewed therethrough. The use and operation of this embodiment of my invention is substantially the same as that embodiment hereinbefore set forth in detail.

In Figure 8 I provide a relatively short cylindrical casing 5b, and on one wall thereof is provided an elongated longitudinally extending slot 6b. Arranged within the casing 5b is a plurality of rings or annular members 13 as shown to advantage in Figure 8. On the outer periphery of each of the rings 13 the same is provided with a series of numbers arranged thereon, the numbers being from naught to nine, while adjacent each of the numbers the said rings are provided with pin receiving openings 14. The rings are adapted to be individually rotated within the cylindrical casing for bringing any predetermined number thereon in registry with the slot 6b all in the same manner and for the purpose as indicated in regard to the other forms of the invention previously described.

In that form of my invention indicated to advantage in Figure 10, I provide an elongated hollow cylindricalr casing provided at opposite ends thereof with attaching ears or flanges, the casing being designated by the reference character 5c and the apertured attaching ears by the reference character 6c. On the front wall thereof, the casing 5c is provided with a plurality of elongated slots 16, which slots 16 are arranged thereon in longitudinal spaced alignment. Arranged within the casing 5c are a plurality of series of rings similar to the rings 13, the series offrings being designated generally by the reference character 17. Piston rings are in every detail an exact replica of the rings 13, a detail description thereof being unnecessary. In the casing 5c the series of rings 17 are of sufficient number as to have series of rings to each of the slots 16. Over one end slot 16 there may be printed on the front wall of the casing the words Change oil, over the next adjacent slot Water in hat, also over another of the slots may be the words Rear and trans. meaning the rear end and transmission. and the other end slot 16 the word Grease. A slot 16 forming the eXtremed end slots is formed in the front wall of the casing and in rlongitudinal spaced alignment with the slot 16. Withinthe casing 5c opposite to the slot 16 I provide a ring 14', on the outer periphery of which ring will be printed or otherwise' formed. preferably in abbreviated form the name of the month of the year. In connection with this ring 14 I would utilize two of such ringsV 13 for indicating the day of the month as is illustrated to advantage in Figure 10.

Manifestly with this last form of my invention, a check up may be made on the oil, battery, rear end and transmission, and the greasing of the various parts of the automobile. Of course, the manipulation of the individual rings of the several series would be the same as described in regard to my other forms of invention, and this form of the invention will, of course, be also usedin connection with the speedometer of the automobile.

Manifestly, any form of suitable attaching means may be utilized for supportingthose forms of my invention shown more particularly in Figures 5 and 8, whereupon the den vice may be readily used by the operator of the automobile.

It is believed that from the foregoing description, a clear understanding of the construction, operation, utility and advantages of an invention of this nature will be had without amore detail description. e

Even though I have herein shown and described the preferred embodiment of my invention, it is, of course, to be clearly understood that I do not wish to limit myself to the specic details of constructiomvthe material views, size, shape and similar details as fall within the spirit of the invention as herein described, -orvthe scope of `the ap- Y pended claim.

Having thus described my invention, what i I claim as new is A recordingdevice for automobiles, comprising a casing adapted to be carried lin.

horizontal position by the instrument board of an automobile and havingin its front Wall' at an intermediate point in its length avertically extending sight opening and also having on its back wall a plurality of spaced longitudinally extending flanges at right an- K gles to said sight opening, the spaces between said flanges havingbacks with longitudinally disposed corrugations, and longitudinally disposed slide'plates, of a less length than the interior of the casing, disposedV and movable endwise between said flanges and at right angles to said sight opening and frictionally contacting with said longitudinal corrugations and snugly held thereagainst by said front wall, and bearing numerals, and having at intervals of their length spaced minute apertures for the engagement e of an adjusting pin introduced through said sight opening. n Y
